MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 00h 43m 25.67s +41d 12m 11.0s on 2014-12-05.60549 UT. The OT unfiltered magnitude is 16.9m (limit 18.6m). The OT is seen in 7 images. There is no minor planet at this place. We have reference image without OT on 2011-12-16.67293 UT with unfiltered magnitude limit 21.2m. The object was present on MASTER-Kislovodsk image on 2014-12-04.60245 UT at unfiltered magnitude 17.7 (limit 18.8m). It was not visible on 2014-12-03.60257 UT image (limiting magnitude 18.0).

The OT is located 467" east and 237" south of the nucleus of M31 = NGC 224 galaxy. It is identical to Possible Nova PNV J00432572+4112119 discovered by Koichi Itagaki on 2014-12-05.454 UT. MASTER-Kislovodsk observations are constraining the outburst time between Dec. 03.602 and Dec. 04.602 UT.
